It would be nice if they could stay that way forever, but that is not reality. You can prolong this appearance though, by using Teflon protection.

Teflon is an invisible shield around each fibre of carpet, which resists soil and stains. It repels most liquids, allowing spills to be removed before staining can occur. Dirt and stains cling to untreated carpet and quickly become embedded in the fibres.

Teflon treatment prevents dirt from sticking to the fibres, making the carpet easier to care for. Teflon must be professionally applied by your carpet cleaner. It is applied by spray application, dries quickly and leaves no odour. It is non-toxic and safe to use around your family and pets.
